Current Developments in Nuclear Density Functional Methods
Jacek Dobaczewski
Abstract:
Density functional theory (DFT) became a universal approach to
compute ground-state and excited configurations of many-electron
systems held together by an external one-body potential in
condensed-matter, atomic, and molecular physics. At present, the DFT
strategy is also intensely studied and applied in the area of nuclear
structure. The nuclear DFT, a natural extension of the
self-consistent mean-field theory, is a tool of choice for
computations of ground-state properties and low-lying excitations of
medium-mass and heavy nuclei. Over the past thirty-odd years, a lot
of experience was accumulated in implementing, adjusting, and using
the density-functional methods in nuclei. This research
direction is still extremely actively pursued. In
particular, current developments concentrate on (i) attempts to
improve the performance and precision delivered by the nuclear
density-functional methods, (ii) derivations of density functionals
from first principles rooted in the low-energy chromodynamics and
effective theories, and (iii) including effects of low-energy
correlations and symmetry restoration. In this study, we present
an overview of recent results and achievements gained in nuclear
density-functional methods.
